The Earthquake Bar
As the Bamboo Bar grew in popularity, some lifters began using it more without the Safety-Slots. In fact, what they were calling for was a BandBell Bar that could hold a lot of bands and a lot of weight, all at the same time. Enter the Earthquake Bar!
The Earthquake Bar was specially designed to hold a huge amount of weight and can be setup in a multitude of ways with bands and weights. Instead of safety slots, it has two-inch grooves cut into the wood to channel and grip the bands as the Bar bends radically under super-heavy weight. Use it for squats, bench, deadlifts, etc. This design works perfectly for CrossFit, high-performance & functional athletes, powerlifters, bodybuilders and general workout programs because it has the unique capability of teaching perfect form however it’s used.
